These subs are great, i picked one up from custom sounds in st.louis on clearance to start my system with, i'm using a cheap OLD L.A sounds amp running somewhere between 120 and 180 bridged to this sub, the subs in a buddies house box in my trunk, the box is huge way over recommended box size and it has a ton of air leaks, one of my old coats is actually helping to seal some of the leaks lol, this sub hits beautifully in this setup, the bass is alittle loose on higher notes but the lows, like 50 cents in da club hits smooth and hard, i'll give another reveiw when i build my new box, as for features, the lead wires are nice and long so i dont see them ripping out easily, the magnets huge, the foam is decent i've seen better but its not a huge issues at these power levels, the connectors leave alot to be desired, for such a good sub it uses cheap push on connector ends other than that it seems pretty good.
